Title:
METHOD FOR PRODUCING PULP FIBERS FOR CARBOXYLATED CELLULOSE NANOFIBERIZATION, AND PULP FIBERS FOR CARBOXYLATED CELLULOSE NANOFIBERIZATION
Document Type and Number:
Japanese Patent JP2021123807
Kind Code:
A
Abstract:
To provide a method for producing pulp fibers for carboxylated cellulose nanofiberization capable of forming a carboxylated cellulose nanofiber excellent in balance between handleability and physical properties.SOLUTION: A method for producing pulp fibers for carboxylated cellulose nanofiberization includes a fiber formation step in which an ozone-containing gas is supplied to a treatment solution having a pH of 6.5 or lower in which wood pulp fibers are immersed so that a CT value, which is the product of the ozone concentration in the ozone-containing gas and the treatment time, exceeds 6,000 ppm/min, thus the method can produce the pulp fibers for the carboxylated cellulose nanofiberization which are formed from the above wood pulp fibers.SELECTED DRAWING: None
